The Duff Truck is a red truck with the words Duff stamped on the sides.
The Duff Truck's good toughness gives it high durability and damage capability, but due to its other stats being abysmal, namely speed and acceleration, it is quite difficult for it to pursue mission objectives, and the poor handling makes it very hard to steer. Overall, it is advised to avoid the Duff Truck in favor of a more practical vehicle for tackling missions.
- This vehicle, along with the Donut Truck are two of the slowest vehicles in the whole game.
- There's a stationary Duff Truck with an air vent parked near the Kwik-E-Mart in levels 1, 4 and 7, but unlike the purchasable Duff Truck from Gil, it cannot be driven.
